ll/EE'IAL RESILIENT RAILWAY-TIE.

Specification of Letters Patent.

Patented Nov. 24, 1908.

Application filed May 4, 1908. Serial No. 430,683.

To all whom it may concern:

Be it known that I, GEORGE MAoKAY, a citizen of the United States,residing at the Ebbitt House, city of Washington, District of Columbia,have invented a New Metal Resilient Railway-Tie, of which the followingis a specification.

My invention relates to improvements in railway ties in which a flangedbase conjoined with resilient rail-chairs constitute the tie; and theobject of my improvement is to obtain a safe, durable and dependablerailway tie. I attain this object by the tie illustrated in theaccompanying drawings, in which:

Figure 1, shows a full side view of the tie; Fig. 2, a full top view;Fig. 3, a cross section through the chair; Fig. 4, a side view at thechair; Fig. 5, a longitudinal section through the chair; and Fig. 6, atop view at the chair.

The rail-fastenlng shown is my Patent No. 889471, dated June 2, 1908.

Similar letters refer to similar parts throughout the several views.

The base A is an angle-plate with upright flanges a-a. The rail-chairsare designated by BB, each of which is an angle-plate with a top 6, andturned-down flanges cc. To each chair-flange is attached a center plated, and an inner-plate e, the center-plate not being as deep as theadjoining plates thus forming recesses 0r slideways 41-4), in bothflanges, to engage the respective flanges aa of the base A. Each chaircontains right and left spiral springs fg, one within the other; eachchair is secured to the base by a vertical center-bolt m, which isintroduced through anopening Z, in the top 6. The

head is held by the washer is which is attached to the top 6. The centerbolt passes through a bearing-plate j, supported on the springs, and isfitted with a sleeve h, within the springs, the lower end of which worksin an opening 2', in the base A; below the base the bolt-end is providedwith a stop-washer n, and a nut 0.

p, is an angle-rin which engages a c linder 9, that shields t e springsfrom bal ast; engaging angle-rings rs, guard the springs at the opening5, in the base A; stud-bolts t, t, tt protect the slideways 'v v.

The springsat rest-maintain the recesses or slideways between each chairand the base, and they permit the chairs and the center-bolts to yieldand recover when actuated by a load on the rails.

The chairs are adjusted and secured to the base by the verticalcenter-bolt and this bolt controls the limit of their resiliency.

What I claim as my invention and desire to secure by Letters Patent, is:

A metal resilient railway tie comprising a flanged base with resilientrail-chairs; the sides of the chairs being provided with slideways toengage the flanges of the base, each of said chairs being secured to thebase by a center bolt, and provided with double springs.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
